Endodontic Therapy: Instructions Following Root Canal Therapy

Please follow the guidelines below. Call Dr. McCallum if you notice any unusual symptoms.

If you have any questions or concerns, call our office at 519-828-3895. There is always a doctor on call when the office is closed.

Since anesthetic has been used, parts of your mouth may be numb for several hours after the appointment.  Avoid chewing and hot beverages until the numbness has worn off.


Take all prescribed medications as directed by Dr. McCallum or Lovell.

If antibiotics are prescribed, continue to take them as directed, even if all signs and symptoms of infection are gone.


You may experience some discomfort on the tooth that has been treated. This may last anywhere between 7-10 days. Swelling in the affected area may also occur. These are not unusual post-operative events.

  • Alternating an anti-inflammatory medication (eg. ibuprofen, naproxen) with a Tylenol-based medication (eg. Tylenol) is recommended (ie: start with ibuprofen → 3 hours later → Tylenol → 3 hours later → ibuprofen etc.).


To protect the tooth and keep the temporary filling in place, avoid eating hard or sticky food (such as gum), and try to chew on the other side of your mouth.  Usually, the last step in a root canal is the placement of a crown or permanent filling in the tooth.  A crown will protect the tooth from breaking in the future.

Oral Hygiene

Continue to brush and floss normally. 

If you have signs of swelling or increasing pain, or if you have any further questions or concerns, please contact our office.
